So let's start with the basics. *Why* does the boiler need to be
replaced. The only compelling reason in my view would be if it was
broken and couldn't be mended through lack of spare parts. Even
then, I would question how hard anyone had looked for spares.

I quite agree, repairing the boiler would be the only low cost
compliant option. Why not tell us more about the boiler.


It's a Glow Worm KFB50. It's had a new fan, been serviced, new pilot
jet, new thermistor, refurb control board, had the pressure
retwiddled and all sorts.

It doesn't light reliably (spark ignition just sparks indefinitely)
unless the cover is left slightly propped open (which I know is
somewhat dodgy - but it's in a well ventilated kitchen with a CO
alarm right next to it). and now it's stopped even that. So it's time
to go, I think.

There may be something wrong with the spark gap - which should be fixable.
My Baxi Solo won't fire if the two screws holding the outer casing on are
done up tight. I presume that they distort something slightly and screw up
the spark gap. Slacken them just a bit, and it's fine!
